okay, this should be a very easy one

How unlike reality; all the physicians are male. No idea what game it is though.

Theme Hospital

yes. your turn.

Next

No guesses, 3rd an arguably best game made from the Trilogy of movies, maybe time for another pic, top down horse back from first level, pie throwing contest or even the duck shoot type game!

Back to the Future 3?

Yeah it is, first level is Doc Brown on horseback side scrolling like you see there and then it changes to top down view where you have to shoot / avoid Injuns and Cavalry. Have to do it in decent time t save the woman from going over the edge of the cliff.

It is the C64 version of the game

I looked for a very long time at Wild West games on the C64 (those chunky graphics are a give away),
before your clue gave it away.
I better pass the baton to someone else as my choices are always too obscure (Speccy games, mostly)

Well, in that case, I'll take the baton...and instead of an obscure Speccy game, I'll throw out an obscure DOS game (CGA, as I am wont to do).

Mach 3

Yep, that's the one. As per usual, when you say that something's obscure, someone gets it in 15 mins :P

Wasn't very hard for me as I suggested the wish - only 6 votes as of yet :(

Funny thing is, if I ever got to guess a game correctly again, I was going to post a screenshot of Mach 3. I think it wasn't featured before in this thread.

I absolutely loved the wonderful splash screens in the game.

Yep, those title screens are really striking. Oh, and the transition between different palettes when you get far into the game is also pretty cool.

Anyway, feel free to post another Mach 3 screen :P

Here's my riddle.
